Thank you for your visiting our UHMWPE fiber.Sincerely hope that our uhmwpe yarn is the perfect material you are searching for.

UHMWPE fiber, also called High Strength and High Modulus Polyethylene Fiber, is currently the highest strength and modulus fiber all over the world. UHMWPE fiber made of 1 million ~ 5 million molecular weight polyethylene, ranks among World Three High Performance Fibers, with nomex Fiber, carbon fiber.

1. Special Performance of UHMWPE fiber (1) high specific strength, high specific modulus.Its specific strength is more than ten times of the same wire, and specific modulus ranks only second to superfine carbon fiber. (2) low fiber density, which is 0.97 0.98 g/cm3, and helps the fiber to float on water surface. (3) low elongation at break and big specific work of rupture, makes it have strong ability to absorb energy, thus it has outstanding impact resistance and cutting resistance. (4) UHMWPE fiber can resist ultraviolet radiation, neutron and gamma rays, and has higher specific energy absorption, low dielectric constant, as well as high electromagnetic wave transmission rate.(5) It also has characteristic of chemical corrosion resistance, abrasion resistance, and long flex life.2.Physical Properties of UHMWPE Fiber
